Anaphylaxis Definition: Anaphylaxis (a-na-fi-LAX-is) is a life-threatening allergic reaction that can occur quickly (as fast as within a couple of minutes). Symptoms of anaphylaxis vary, but can include hives, itching, flushing, and swelling of the lips, tongue, and roof of the mouth. The airway is often affected, resulting in tightness of the throat, chest tightness and difficulty breathing. These reactions can also be accompanied by chest pain, low blood pressure, dizziness and headaches. Anaphylaxis can be caused by a number of  triggers, including but not limited to certain foods, stinging and biting insects, medications and latex.


Make sure you speak with your health care professional about how to identify the signs and symptoms of anaphylaxis.




Symptoms of anphylaxis may include:

• trouble breathing

• wheezing

• hoarseness (changes in the way your voice sounds)

• hives (raised reddened rash that may itch)

• severe itching

• swelling of your face, lips, mouth, or tongue

• skin rash, redness, or swelling

• fast heartbeat

• weak pulse

• feeling very anxious

• confusion

• stomach pain

• losing control of urine or bowel movements (incontinence)

• dizziness, fainting, or “passing out” (unconsciousness)

If you, your child or someone you're caring for shows signs or symptoms of anaphylaxis, immediately call 911 and seek emergency medical attention.
